Decorations are used when you want to bring the tank to life, with a variety to choose from. From fake decorations to varieties of live options, you have multiple ways of showing off your tank. Although fake decorations are the easier route, the live decorations bring more than just looks to the scene. It's like making your own little ecosystem in your very own house. It looks great and changes so many aspects that it's one of the most preferred methods for many  fish keepers.
